How are you meant to reply to "What's up?!"?

i totally understand your situation..just answer with hey or your cholesterol fatty!!
i don't know its awkward

Oh, God! I'd really love to know, because I often don't know how to respond, and this has been going on for like, 10 years!!! I usually say "not much" because I don't know what to say. I know it's a way of saying "hey, how are you?" but you can't really respond to "what's up?" by saying "good, and you?"!

It depends on.....the weather...when they ask what's up you say umbrellas?!?, when its windy you might say my skirt if you're a girl and my tie if you're a guy.
......your mood....when asked and you're happy you'd say my frown (get it? it's now a smile since it's up) or when you're angry or sarcastic you'd go clouds, birds and the like.
......the person you're talking to....a what's up from a friend would almost immediately be combined with a handshake or a kiss. however for new acquiantances it could be a nod or a nothing much reply.

Well usually I'm sarcastic and say "The cieling" or "The sky" but you can always stick with the whole "Nothing, Whats up with you?" routine, works just as good!

I usually say "The sky" and they go huh and i repeat " What's up?" so reply is the sky!!!

Oh, another one - when a close friend trips such as trips over something such as fall down - say "Had a nice trip? See ya next fall.." and don't forget to help them up!

Cheers!

Oh Plenty!!!! There is so much happening ... its crazy! How about you? :D This really has the asker stumped most times... Its a dumb question... prolly mainly asked to catch up on your life with the best intention. But I do find it facile.

When bros say that to me, I respond with, "Jess chillin'" or something to that effect. Respond however you want. Whatever makes you comfortable and fits your personality.

BTW, hey baby, what's up?

whats up means what r u doing....reply with nothin much just listening 2 music or just checking my mail or whatever ur doing

My favorite thing to say is "whole lada jack nada" its a one of a kind phrase to combat the most used phrase ever

Since they're really just saying "hello," I simply reply "hey," "hello," "not much," or "nothing."

ok heres whats up.......
airplanes

if its early in the morning you could come back w/ ME lol
